2.0202.1a
Removal

With the occupant's permission, unvented heaters will be removed except when used as a secondary heat source and when it can be confirmed that the unit is listed to ANSI ANSI American National Standards Institute, www.ansi.org Z21.11.2

Units that are not being operated in compliance with ANSI ANSI American National Standards Institute, www.ansi.org Z21.11.2 should be removed before the retrofit but may remain until a replacement heating system is in place

Failure to remove unvented space heaters serving as primary heat sources has the potential to create hazardous conditions and thus any further weatherization services will be re-evaluated in the context of potential indoor air quality risks

Eliminate sources of combustion byproduct within a living space

2.0202.1b
Occupant education

Occupant will be educated on potential hazards of unvented combustion appliances (primary or secondary) within a living space

Inform occupant about possible hazards associated with combustion byproducts and moisture
